below thing solved mine

sudo vim /etc/NetworkManager/system-connections/ConnectionName
set this : password-flags=0

next time this will store your password.

Seems to be a duplicate of Network manager forgets wireless password after sleeping or powering off

You might find it useful to set the connection as "available to all users", or remove duplicate connection configs for the same wifi

also, it's probably related to this known bug

This usually fixing that issue with your device it changes the encryption from hardware to software.

Run the commands one line at a time, just copy and paste for accuracy.

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

sudo modprobe -rfv ath9k

sudo modprobe -v ath9k

Thanks

I know it sounds strange but I have the experience that in a case like this it might help to reboot your router.

Also check if the packet "wpasupplicant" is installed.

You need to explicitly call the dhclient and make it assign your wifi an IP.

sudo dhclient wlan0.

This works on Ubuntu 14.04.

The problem may be that netctl is still controlling your network connection. This worked for me

# systemctl disable netctl-auto@[interface_name].service

You may also have to run the "systemctl stop" command for this as well.

try changing the name and password of router,so that PC identifies it as a new network. Then connect to it. It works for me.
